Letters Patent No. 106,879, dated August 30, 1870.

IMPRvnn MEAT-CHOPPER.

The Schedule referred to in these Lettera -Patent and making puri:` of the same.

To all whom it may concern'.-

Be it known that I, ALBERT 1t. Slaven, ot Salem, in the county of Columbiana andState of Ohio, have invented certain new and useful Improvements in Machines for Ghopping Meat; and I do hereby dcclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specicution, in whichl Figure 1, plate 1, is a side elevation of the front of the improved machine.

Figure 2, plate 1, isa side elevation of the machine.

AFigure 3, plate 1, is a top view.

Figure 4, plate 1, is a top view ot the n'iachine as seen when the meat-tub is removed.

Figure 5, plate 2, is a vertical section taken centrally through the machine, looking toward the front thereof. Y

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain novel improvements on machines for chopping meat, wherein a rotating tub is employed in combination with. vertically reciprocating knives.

The nature of my invention consists- First, in the construction of the main casting or center, to which` the several parts constituting the machine are connected, in such manner as to adapt it to aiord a solid s upport for and a means of holding in place the 'rotating tub; and, also, adapt it to receive audhave secured directly to it the legs on which the machine is mounted.

Second, in the application to the central vertically reciprocating rod,'carryiug the choppingknives, of a fixedhub having on each side a feather, thus forming a cross-l1ead, which is held in place and guided by grooved anti-friction rollers, for the purpose of preventing'frictiou between said rod and its bearing in the main casting; and, also, for the purpose of preventing lateraldisplacement and undue friction of the pitman joints which connect the said rod to the flywheel.

Third, in connecting the vertically moving rod, carrying the cutters, to the fly-wheel, by means of' a pitman rod, when said cutter-carrying rod is guided by a cross-head working between rollers beneath the rotary tub.

Fourth, in providing for giving 'an intermittent rotary motion to the meattub,in combination with a regular reciprocating motion given to the cutters, the motions of the said tub taking place during the ascent of the cutters, thereby carrying fresh portions of meat beneath the latter at every stroke, and holding the tub momentarily at every act of cutting; all of which will be hereinafter described.

A represents the hed or center of the machine,

which is a casting, presenting on top an annular rib,

a, and a central vhollow and upwardly tapering -bea'ring, B, with the vertical axis of which the rib is con'- centric. v y

This bed is, also, constructed with askirtingaround its four sides, the angles of which receive and have secured into them by bolts, c, the legs B', on which the bed A is mounted.

Upon the annular rib aof the bed A is supported a ring, C, having cogs, e, around its lower edge, which engage with a pinion spur-wheel, i, ou the hub n, of a radially notched stop-wheel, N.

This tooth-ring O is pcrmanentlyisecured to the bottom of the meat-tub, which consists of a circular chtmping-block, D, and a hopper, E.

rlhrough the center of the chopping-block I) a hole is made through which the tubular bearing B passes, land into which a shield, J, is fitted, that terminates upwardly in a cone, and prevents' the meat from getting down into the opening through the block D or about the tubular bearing B.

rlhrough the tubular bearing B' and through the upper contracted end of the shield J a rod, g2, passes freely, which has secured to, its upperr end by a setscrew, a knife-head, G, carrying' two straight-edge knives, G' G. These knives are parallel to each other; they extend across the chopping-block, and their cutting-edges are parallel thereto. By giving vertical motion to the rod y, the knives are caused to cut through or chop up anything which inay be placed into the tub as rapidly as it is moved beneath them.

The knife-,rod g2 extends down through its tubular bearing B, and is prevented from having any vibration laterally by means of feat-hers, s s, which are formed on a hub, K, that -is secured fast to said rod, thus constituting a cross-head; which is held between and guided by two grooved anti-friction wheels, 7c k, be-

neath the bed A.

The grooved wheels 7c k have their bearings ou and turn freely about the short shafts l l, which are applied to a plate that is secured beneath" the bed A. lf desirable, these anti-friction wheels may be made adjustable, so that they can be set-up to accommodate for wear between the feathers ofthe vcross-head and the grooved peripheries of theanti-friction wheels 7c k.

The lower end of the knife-rod is pivoted at t, iig. 5, to the upper end of a pitmau rod, g, the lower en d of which is connected by a wrist-pin, g, to the face of the hub ot' a balance or iiy-wheel, F'.

The shaft f of the fiy-wheel F has its bearing in a hanger which is bolted to the bottom side of the bed A, and, on `the outer end of this shaft f, a. pinion spur-wheel, h, is keyed, which engages with teeth on the driving-wheel L. v

The wheel L is provided with a crankbandle, H, and it has its bearing ou a short shaft which is secured fast to the i'out side of the bed A.

0n the inner sideof wheel L, and concentric to its axis, is a circular plate, P, having;` four studs, r, projecting from it, and arranged concentrically about its axis at regular distances apart.

These studs are designed to enter radial notches made into the circumference of a stop-wheel, N, and give to this wheel an intermittant rotary motion.

.On the short hub u of ivbeel N the pinion which moves the tub is keyed; consequently, the tub will partake of the motions given to the wheel N.

The movements'imparted to the knife-rod g2 are so adjusted, with respect to the intermittent movements imparted to the meattnb,fthat the latter is moved during the ascent of the cutters, and is held stationary duringthe act of cutting; thereby fresh portions of meat are moved beneath the cutters at each stroke thereof.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. The construction of the bed or center A with annular bearing rib a, and a central tubular bearing -B, and, also, with the legs of the machine secured directly to it, substantially as described.

2. The cross-head guide K s s, applied to the kniferod y2, and working between anti-friction wheels k k, substantially as described.

3. The knife-rod g, connected to the iiy-wbeel IF by means of a pitman g1, and prevented from lateral displacement by means of a cross-head working between wheels beneath a rotary tub, substantially as described.

4. Communicating a regular reciprocating mot-ion to the knife-rod g2 by means of Wheels L,h, and F anda pitman, g1, in combination with means which will give an intermittent rotary motion to the meattub, substantially as described.
